LANTERN.

Application filed December 10, 1915.

To @ZZ fw hom t mag/,concern Be it known that I, GEORGE A. MARsI-I, a citizen of the United States, residing at Norfolk, in the county of Norfolk and State of Virginia, have invented certain new and useful Improvements in Lanterns; andv I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to improvements in lanterns and more especially to that type of lantern wherein` means is provided for producing a different colored light, for instance, a white or a red light, for use in signaling. y

The invention consists in certain novel details of construction and arrangements and combinations of parts all as will be now described and particularly pointed out in the appended claims.

Referring to the` accompanying drawings,-Figure 1 is a side elevation, partly in section, of the'lantern. Fig. 2 is a top plan view, omitting the top, the guard and the globe. Fig. 3 isa section on the line 3-3 of Fig. 2, looking in the direction of the arrow. Fig. 4 is a bottom plan view. Fig. 5 is a. sectional view on the line 5 5 of Fig. 4, looking in the direction of the arrow. Fig. 6 is a detail view of the wick actuating means. Fig. 7 is a detail view of one of the hooks for holding the shield in its lower position. Figs. 8 and 9 are detail views of the shield.

Like reference characters throughout the several figures indicate the same parts.

In the drawings, 1 represents the body portion of the lantern having the ventilating perforations 2 therein and the ordinary globe 3 and wire guard cage 4, all mounted on the body portion in the usual manner. rlhe base 5 of the lantern is detachably secured to the body by spring latch 6 (Fig. 2) and is provided with apertures 7, 7, 8, 8, 9, 9, and 10 (Fig. 4) for a purpose presently to be described. Secured to the base 5 are a plurality of upwardly extending rods 11 (Figs. 1 and 3) preferably connected at the upper ends by an annulus 12the connections at the ends of the rods being preferably formed by nuts 12a, as shown. Mounted to slide on the rods between the base and annulus is a shield 13, preferably a cylinder of translucent material, suitably colored, said cylinder being formed of two semi-cylindri- Specication of Letters Patent.

cal sections, retained between spaced annuli 14, 14a having shield retaining lugs 15. The annuli 14, 14a are of greater breadth than the thickness of the cylinder to form inwardly extending flanges, to the lower one of which upwardly extending rods 1G are secured, in any suitable manner. Rods 16 are of a greater length than the height of the cylinder and extend upwardly through annulus 14a, saidrods being provided at their upper ends with enlargements 16, usually formed by nuts 1Gb. To facilitate the removal and replacement of the sections because of breakage, or when it is desired to clean the shield, springs 17 are mounted on rods 16 between the enlargements 16EL and the upper annulus. Normally, springs 17 tend to press the annulus 14a downwardly so that the lugs 15 engage the outer surface of the sections, but by elevating annulus 14a a sufhcient distance as to raise the lugs 15 thereof above the top of the cylinder or shade, any or all of the sections may be readily removed from between the annuli. Said inwardly extending fianges formed by annuli 14, 14a are also provided with apertures for rods 11 whereby the shield 13 is guided and permitted a vertically sliding movement. A cushioning effect is obtained between the. glass cylinder and annuli 14, 14"L by inserting between the ends of the cylinder and each annulus an asbestos gasket 18. An elevating spring is providedv for the shield, said spring preferably taking the form of a large spiral spring 19 interposed between the base 5 of the lantern and the lower annulus 14 of the shield, said spring, when released, being adapted to raise the shield to a point opposite the iiame of the lantern.l Mounted on each of the rods 11, intermediate the upper annulus 14:L of the shield and the annulus 12 is a spiral spring 20, these springs being adapted to absorb the blow of the shield when said shield is elevated by the spring 19.

To hold'the shield below the flame against the tension of spring 19, the inwardly exltendingflange, formed by the bottom annulus 14 of the shield, is provided with two downwardly-projecting hook-shaped members 21, which, when the shield is in its lowered position extend through apertures 7, 7, in the base and are engaged by a latch 22, pivotally mounted on the under side of the base 5 preferably on a central rivet 23.

AYbers 26, 26, connected at their lowerends by a crossbar 27, is slidably mounted in the `ba'se'offtheV lantern (Figs. 3 and4)r and Latch 22 is normally held in position to engage the hooks 21 by a spring 24 interposed between a downwardlly extending projection 22a on one end of said latch and a projection 25 struck up from the baser of the lantern. ,Y

-For depressingtheshield below the level of the fiame a yoke,rconsisting of side memloosely connected within thev shield., The

cross bar -27'is located below the baseand is normallyrheld up by a springlatch 28 extending upwardly Vfrom the crossbar through v oneof theapertures 8 inpositionto engage y Vthe upper sideof the base. The side mem- Y 1 bers26 extend from the cross bar upwardly' through apertures 8, 8, in the base anda-lso 'through apertures 18? in the lower flange or Vannulus 14 of the shield.l` At their upper ends they are enlarged'as at 29 forming Vheads larger' than the diameter of theopen- 'ings inthe annulus 14 through which the dependently of the shield,yand held in that position 'by the latch 28. Y

VVh'en in'its lower position (Figs. l and 3) the shield is below the burner so that when lighted theV lanternV will display a white light, .but when elevated the shield surrounds or envelops the lame, when the lanternwill'display a red or other colored light, according to the color of the shield. Mounted on theV base within'the shield is an oil" pot 30,- carrying the wick holder and `burner 36, the oil-potpreferably being removably secured Vto the base by screws 31 Y passing through( openings 49, 9 in the base,

and the heads of the screws being engaged on 4the under side of the base by Va latch-33 i pivotally mounted on rivet l23 (Fig. 4). A

tube 34 mountedfinthe oil pot extends below 'the base oiV the vlantern through -the aperture 10 andupwardly to a point in the top lof'thewoil pot adjacent a gear wheel 35 which latter is adapted to raise or lower a Ywick in the fburner 36 inthe usual manner.

e In'lanterns'ofthistype it is desirable that i' Vat means be provided for adjusting the-wick lwithoutv thenecessity otraising the globe, `and for actuating the wheel '35j from the exterior, without raising the globe, va'bar 37, A provided at its upper end with teeth 38,

adapted to engage wheel 35, extendsupwardlyvthrough tubeV to the wheel 3 5. VVBar 37 is` provided, on one of its edges at` a point intermediate its'ends, with a curved with the gear wheel 35.

tion independently of the yoke.

Y projection 39, this projection being adapted to abut against the wall of tube 34 to form a` pivot upon which the bar may be swung in a vertical plane to throw the teeth 38 on its upper end into and out of engagement When the teeth 38 and wheel 35 are in engagement the wick may be raised or lowered by an upward or 'downward movement of bar 37 and when said teeth and wheel are out of engagement with one another the bar 37 is prevented from Yfalling yout of the tube by a pin 4 0 which projects from one side of the bar and engages the top of the oil pot. The bar also hasits lower end below the base of the lantern bent to'form a finger piece 41 by which it may be operated in a convenient manner.
